Low Pin Count LPC Bus Interface Signals

32580B	Signal Definitions

3.4.8Low Pin Count (LPC) Bus Interface Signals

Signal Name	Ball No.	Type	Description	Mux

LAD3	L29	I/O	LPC Address-Data.Multiplexed command, address,	GPIO35
			bidirectional data, and cycle status.
LAD2	L30		bidirectional data, and cycle status.	GPIO34
LAD2	L30			GPIO34

LAD1	L31			GPIO33

LAD0	M28			GPIO32

LDRQ#	L28	I	LPC DMA Request. Encoded DMA request for LPC	GPIO36
			interface.
			Note: If LDRQ# function is selected but not used, tie
			LDRQ# high.

LFRAME#	K31	O	LPC Frame. A low pulse indicates the beginning of a	GPIO37
			new LPC cycle or termination of a broken cycle.

LPCPD#	K28	O	LPC Power-Down.Signals the LPC device to prepare for	GPIO38/IRRX2
			power shut-down on the LPC interface.

SERIRQ	J31	I/O	Serial IRQ. The interrupt requests are serialized over a	GPIO39
			single signal, where each IRQ level is delivered during a
			designated time slot.
			Note: If SERIRQ function is selected but not used, tie
			SERIRQ high.
